In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

Read part 1 of this series on construction and operating principles here. Having understood the construction and basic operating principle of BLDC motor in the first part of this article, it becomes ...

The circuit in this Idea for Design provides three levels of speed control for a dc motor using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from ...

Stepper and permanent-magnet synchronous motors increasingly serve control applications that require a high degree of efficiency and outstanding performance. Current technology for motor control ...
